Hidden Gem Submission Page Unresponsive

The Photoshop Evangelist 'Hidden Gem' competition upload page is unresponsive. I've spent hours recording, preparing and attempting to upload three videos, only for the Upload Page to fail every time. File size can't be an issue (videos are about 3-4 mb each) and I've taken care to meet all the criteria, to no avail. It's been a complete waste of time.
